labelingia

Labelingia is a genus of fungi in the family Tricholomataceae. The genus was described in 1916 by Finnish mycologist Elias Robert Laine. Species within Labelingia are typically small to medium-sized mushrooms with a convex to flattened cap and a slender stipe. Their gills are often adnexed to decurrent and white to pale in color. The spore print of Labelingia species is usually white.

Species in this genus are saprobic, meaning they obtain nutrients from decaying organic matter. They are often found growing in terrestrial habitats, such as forests, woodlands, and grasslands, frequently associated with mosses or decaying wood. The distribution of Labelingia species is primarily found in temperate regions of the Northern Hemisphere.

The taxonomy of Labelingia has undergone revisions, with some species previously placed in this genus now assigned to other genera. Identification of Labelingia species often relies on microscopic features such as spore shape and size, as well as macroscopic characteristics like gill attachment and cap surface. Research into the ecological roles and potential biotechnological applications of Labelingia species is ongoing.
